Electronic Ballasts

Keystone’s extensive portfolio of electronic ballasts covers all fluorescent lighting applications, including commercial, industrial, and residential type lighting fixtures. Known for their dependability and energy efficiency, every Keystone electronic ballast is “burnt in” at the factory to ensure exceptional performance and superior reliability. Complete with a 3 year factory warranty.

HID Ballasts

Known for dependability and superior efficiency, Keystone’s high intensity discharge (HID) ballasts are perfectly suited for even the most demanding HID lighting applications. Keystone utilizes sophisticated manufacturing and quality control processes to guarantee outstanding performance in the field.

Available in metal halide, pulse start metal halide, and high pressure sodium, as well as ballast replacement kits.

Sign Ballasts

Keystone’s line of sign ballasts makes commercial sign maintenance simple. With only six ballasts that cover virtually all common plastic sign configurations, you’re sure to have the right ballast for the job.

All Keystone magnetic sign ballasts are designed to operate at a minimum starting temperature of -20ºF, which is ideal for use in cold outdoor sign applications. With Keystone’s quality and dependability, you can count on your installation to last.

Magnetic Ballasts

While many other manufacturers have discontinued their magnetic ballast lineup, Keystone remains committed to providing replacement magnetic ballasts for the millions of existing magnetic ballast installations.

Keystone also offers electronic “drop in” replacement to many common magnetic ballasts for simple conversion from magnetic to electronic technology.
